  • All Implemented Interfaces:
    GraphConstants
    public class BIFParser
extends java.lang.Object
implements GraphConstants
    This class parses an inputstream or a string in XMLBIF ver. 0.3 format, and builds the datastructures that are passed to it through the constructor.

      • parse

        public java.lang.String parse()
                       throws java.lang.Exception
        This method parses the string or the InputStream that we passed in through the constructor and builds up the m_nodes and m_edges vectors
        Returns:
        returns the name of the graph
        Throws:
        java.lang.Exception - if both the inString and inStream are null, i.e. no input has been provided
        BIFFormatException - if there is format of the input is not correct. The format should conform to XMLBIF version 0.3
        java.lang.NumberFormatException - if there is an invalid char in the probability table of a node.

      • writeXMLBIF03

        public static void writeXMLBIF03​(java.lang.String filename,
                                 java.lang.String graphName,
                                 java.util.ArrayList<GraphNode> nodes,
                                 java.util.ArrayList<GraphEdge> edges)
        This method writes a graph in XMLBIF ver. 0.3 format to a file. However, if is reloaded in GraphVisualizer we would need to layout the graph again to display it correctly.
        Parameters:
        filename - The name of the file to write in. (will overwrite)
        graphName - The name of the graph. (will be the name of network tag in XMLBIF)
        nodes - Vector containing all the nodes
        edges - Vector containing all the edges
